DTC B1034: Driver Air Bag Initiator Circuit Short to Power CircuitS7RS0B8204021
Wiring Diagram
CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor Connections”.
• If there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The voltage measured at driver air bag initiator ci rcuit is above a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
Step 2: Check driver air bag (inflator) module initiator circuit.
Step 3: Check whether malfunction is in contact coil or driver air bag (inflator) module.
